Two points that I think are worth making

1) When someone in early twenties sets up a successful business it is considerably more newsworthy and is far more likely to get attention than someone in say their 40's, thus distorting public preception.

2) Once you get into your 50's your career options narrow dramatically. You become too expensive, less flexible and potential employers may feel that you are 'stuck in your ways'. Therefore entrepreneurship may in actual fact be a necessity.

heck, your career options can narrow dramatically in your 30's. Especially if you have a startup background with titles like founder, CEO, etc.
